“找不到匹配的分布".在PyCharm中的所有pip安装上 [英] "No matching distribution found" on all pip installations in PyCharm

问题描述

我在运行PyCharm Community Edition 2016.1.2和Python 3.4.3的Windows 7上，并且具有以下行为:

I'm on Windows 7 running PyCharm Community Edition 2016.1.2 and Python 3.4.3, and I have the following behavior:

• 在PyCharm中安装新软件包(通过设置->项目解释器)失败，并显示错误消息No matching distribution found for [package name]，例如No matching distribution found for numpy.
• 在PyCharm中更新软件包(通过设置->项目解释器")声称成功，并显示Package successfully installed通知，但未更改表中的软件包版本(并且实际上未进行更新).
• 使用pip在命令行上安装新软件包(例如pip install numpy失败，并显示与PyCharm相同的错误消息.
• 在命令行上更新软件包后，输出为Requirement already up-to-date并且没有更新.

• Installing new packages in PyCharm (from Settings -> Project Interpreter) failed with the error message No matching distribution found for [package name], e.g. No matching distribution found for numpy.
• Updating packages in PyCharm (from Settings -> Project Interpreter) claimed to succeed with a Package successfully installed notification, but did not change the package version in the table (and did not actually do the update).
• Installing new packages on the command line with pip (e.g. pip install numpy failed with the same error message as PyCharm.
• Updating packages on the command line gave the output Requirement already up-to-date and no update.

什么????

推荐答案

这是pip无法正常连接到互联网时的行为.就我而言，我正在运行Fiddler，因此无法通过Fiddler的代理获得点子.

This is pip's behavior when it can't connect to the internet properly. In my case, I had Fiddler running so pip couldn't get through Fiddler's proxy.

对于其他任何出现这种情况的人:检查您的网络，防火墙，代理等.

To anyone else getting this behavior: check your network, firewalls, proxies, and so on.
